Workers on the Presena glacier in the Trentino-Alto Adige region of the Dolomites in Italy found the bodies at an altitude of 9,850 feet. The glacier has been receding because of an unusually hot summer and the workers were covering it with a giant tarpaulin to keep it from thawing further.

The soldiers are believed to have been from an artillery unit of the Austro-Hungarian army and were killed in 1918. The skeletons were identified by remnants of uniform and insignia. No word yet on whether they can be named.

During World War I, Italy fought against Austro-Hungarian and German forces in the bitter cold of the mountaintops. One favorite tactic was to fire artillery shells above enemy positions to cause avalanches to bury them. In other cases soldiers died from wounds or exposure and were lost. Many of these bodies have been found in later years.

From more on the Italian Front, there is an excellent website and photo collection here.

The Presena glacier isn’t the only one melting. The entire Alps is seeing less ice cover, reducing the number of ski slopes and increasing the risk of avalanches for trekkers.
